Abstract
Abstract A seal for an antifriction bearing comprises a chamber in a slot between the fixed and rotatable member which surrounds the bearing. The slot has an axial component leading from the bearing to the chamber and a radial component leading from the chamber to the atmosphere. Upon rotation, dirt will be centrifugally removed or prevented from entering through the slot to the bearing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
The combination of an antifriction bearing mounted between a fixed member and a member rotatable in respect of the fixed member about an axis of rotation, and a seal for the bearing, wherein the members define therebetween a slot outwardly adjacent the antifriction bearing, the slot having a first component extending substantially radially in respect of the axis and leading to the surrounding atmosphere, and a second component extending substantially parallel to the axis, the rotatable member having a sealing lip facing the first slot component and forming a chamber with a recess in the fixed member, and said slot components being in communication with the chamber, the axially extending second slot component leading from the chamber towards the antifriction bearing.
Claim 2
Dependent Claim
121 words
The combination of an antifriction bearing mounted between a fixed member and a member rotatable in respect of the fixed member about an axis of rotation, and a seal for the bearing, wherein the members define therebetween a slot outwardly adjacent the antifriction bearing, the slot having a first component extending substantially radially in respect of the axis and leading to the surrounding atmosphere, and a second component extending substantially parallel to the axis, the rotatable member having a sealing lip facing the first slot component and forming a chamber with a recess in the fixed member, and said slot components being in communication with the chamber, the axially extending second slot component leading from the chamber towards the antifriction bearing.
Claim 3
Dependent Claim
14 words
The combination of claim 1, wherein the chamber is of substantially toroidal cross section.
Claim 4
Dependent Claim
30 words
The combination of claim 1, wherein the sealing lip terminates at a point farther from the axis than the second slot component is from said axis in a radial direction.
Claim 5
Dependent Claim
21 words
The combination of claim 1, wherein the rotatable member and the sealing lip thereof constitute a major portion of the chamber.
Claim 6
Dependent Claim
43 words
The combination of claim 1, further comprising a sealing element mounted in the second slot component, the sealing element having a radially and inwardly extending flange, and a sealing medium filling a chamber defined between the sealing element flange and the antifriction bearing.
